While liberal groups and bloggers are coalescing around Bill Halter in his primary challenge to Arkansas Sen. Blanche Lincoln (D), Greg Sargent reports that former President Bill Clinton is backing Lincoln.
"Sen. Lincoln asked President Clinton several months ago to support her reelection," Clinton's spokesman told Sargent. "He said he would, and he does."
"[The spokesman] confirmed that this applies to the Dem primary, too, and declined further comment."
